JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.

The FDB seal is made of a helical wound spring and a polymer jacket, It is the best choice for vacuum, gas and low-temperature flange sealing applications.

SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.

JST FHP series is  made of a helical wound spring and a polymer jacket, which is mainly used for piston.

The PTFE gate valve seat seal is made of durable teflon, it is compatible with the Cameron gate valve type FC, FLS, and used in rotating equipment to minimize o-ring movement.

This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
